Application led January 81, 1929. Serial No. 836,879.

Metallic window structures are in many' respects superior to wooden window structures. They arev strictly reproof; are much stronger; will not warp, shrink or swell; occupy 'less space; and will last considerably longer. They are, however, a little too heavy for some classes of installations where li htness in weight is a controlling factor. etallic window structures made of sheet aluminum would not be too heavy for such inn stallations, but no commercially satisfactory aluminum window structure of the sliding sash type-which is the type in greatest demand-has heretofore been produced owing.-

to the fact that when an aluminum'sash is slid up and down in a closely fitting aluminum guide the st iles of the sash stick, scuif up and wear out very rapidly. v

The object of the present invention is to provide a novel aluminum window structure of the sliding sash type which is .not subject to rapid wear, will not stick or scuff up, and will give excellent service for a long perlod of time. .25 While the -foregoing statement is indicative of the nature of the invention, other objects and advantages will be apparent to those skilled in the art upon a full understanding of the construction, arrangement se and operation of the improved sash and guide structure.

Two slightly different embodiments of the' invention are presented herein for the purose of exemplification, but it will of course e appreciated that the invention is capable of being incorporated in various other forms coming equally within the scope of the appended claims. In the accompanying drawings: Fig. 1 is a fragmentaryface view o-f an aluminum sash and guide assemblage constructed in accordance with 4the invention;

Fig. 2 is a horizontal section through thev cooperating portions of the sash and guide, taken on the line 2-2 of Fig. 1; and.

Fig. 3 is a section corresponding generally to Fig. 2, showing a slightly different embodiment of the invention.

The window structure shown in Figs. 1

and 2 includes a sash 10 in which the rails and stiles 11 and 12 are made of sheet alummum. Each stile ofthe sash slides up and downin a guide 13', which guide consists of p a fixed strip 14 which is made of sheet aluminum and a removable strip 15 which is also made of sheet aluminum. The fixed strip 14 is fastened to thejamb 16 of the associated window casing by means of a number of screws 17, and is characterized by a central web portion- 18 in spaced relation to the jamb, two leg portions 19 and 20 which extend from the edges of the web portion into engagement with the j amb, and two reversely bent fiange portions 21 and 22 which extend from the inner edges of the le portions outwardly in slightly spaced relatlon to the same.

The flange portion 22 of the'ixed strip terminates preferably a little short of the plane of the web portion 18, and the removable strip 15-'-which will hereinafterbe referred to as the sash-retaining strip-is positioned partly within the groove 23 whi ch is formed in the fixed strip between the portions 20A and 22 thereof. The sashretain1n strip is detachably secured to the fixed strip by means of a number of rivets or screws 24 which extend crosswise of the groove 23 at regular intervals and engage Within bayonet slots 25 formed in the inner edge of the sash-retaining strip. l

The flange portion 21 of the fixed strip extends considerably beyond the plane of the -web portion 18, and provides a substantially rigid backing for a lining strip 26 of a relatively soft non-metallic material, such as cork, felt, wood, leather, fiber, asbestos, fabric, and`the like, which lining strip extends into the groove 27 which is formed in the fixed strip between the portions 19 and 21 thereof and is held against outward displacement by means of an inturned flange 28on the outer edge of the portion 21. One face of the stile of the sash bears directly against the and down inthe guide, the lining strip absorbs all of the wear and prevents that face of the stile from wearing out.

Another lining strip 29 is 'carried by the sash-retaining strip in spaced parallel relation to the lining strip 26. The sash-retainlining strip, and, when the sash is moved up ing stri forms a backing for the linin strip 29 and 1s provided with an oii'set portion 30 in which the lining strip is held against displacement. The lining strip 29 is made of the same material as the lining strip 26 and performs the same function with respect to the other face of the Stiles with which it is in direct engagement.

As the lining strips become more or less worn away or compacted as a result of continued service, the outer portion of the sashretaining strip is automatically advanced toward the flange portion 21 of the Xed strip by means of a sprin strip 31, which spring strip is secured to t e inner portion of the sash-retaining strip and presses resiliently against the outer wall of the groove 23 in the fixed strip in such a way as to move the outer portion of the sash-retaining strip in the desired direction.

The sash and guide assemblage shown in Fig. 3 differs primarily from that shown in Figs. 1 and 2 in that two sash 32 and 33 are employed instead of one and a single guide 34 accommodates both of the sash. In the guide 34, the two web portions 35 and 36 correspond to the web portion 18, the two flange portions 37 and 38, which are bridged together, corres ond to the flange portion 21, and the two sas -retaining strips 39 and 40 correspond to the sash-retaining strip 15. The flange portions 37 and 38 back vup lining strips 41 and 42 which are held in place thereagainst by the edges of a cap strip 43 secured to the web portion 44 which bridges such flange portions, While the outer portlons of the sash-retainin strips 39 and 40 back up lining strips 45 and 46 The form of attachment of the lining strips is preferably such as to facilitate replacement of the same. In both of the structural embodiments herein shown, the lining strips are preferably made of a material such as cork, leather, fabric or the like which is suflicientl iexible to permit them to be bowed and t en snapped into position. If a less flexible material is employed for the lining strips, and it is desired to have the strips readily replaceable, suitable changes should be made in the construction of the backing elements for the same.
